For Sale How can I change the Proxy Bid in NW?

[InterURL]

I am a newbie of namewinner. I know it is feasible to increase Proxy Bid through 'How To' guidance of NameWinner. However, I could not find the input-box to increase Proxy Bid. Even I did not find where I shall enter the initial Proxy Bid -- I only found a input-box for Place Bid.
Anybody help me?
Thank you very much!

If you have a proxy bid showing of $ 20. and also the high bidder.

If you enter $30 in the bid slot. And, hit submit. It will say "you raised
you max bid to $ 30"

If will then show you as $ 20 as bid price and with a max of $ 30.
when you look at your list of names.

Thank you, actnow. I understand.
I had not entered the figure in the bid slot then because I was afraind of bidding against myself.
I was confused by the nw's system.
